Application filed April "f,

To all whom it may concern:

Be it known that ll, WILL AM L. HILBIsH, a citizen of the UnitedStates'oi America, and resident of Fort Vlfayne, in the county of Allenand State of Indiana, vented certain new and "useful improve ments inFilters, of which the following is a specification.

This invention relates to improvements in water filters for connectioninthe pipe line between a cistern or other sourcdoit water supplyandthedistributing pipe sys tern of a residence, andtheobject thereof is toprovide a filteringapparatus so constructed as to admit of convenientCleansing and renewal of the filtering material without disconnectionor" the apparatus from the pipe line, and which will be easilyaccessible for cleansing and renewal operations.

These objects are accomplished by the construction illustrated in theaccompanying drawings, in which: a

Fig. l is an elevation of a construction embodying the invention, partlybroken away;

Fig. 2 is a plan view of a removable spider used in the. apparatus; and

Fig. 3 is a plan view of one of the filtering drums employed in theconstruction.

The characters appearing in the description refer to parts shown in thedrawings and designated thereon by corresponding 7 characters.

bolts 3. Upon the exterior of the tank are a series of lugs 4 in whichthe respective bolts 3 are hinged, and the head 2 has a correspondingseries of lugs 5 that are on gaged by thumb-nuts 6 on the bolts respectively.

The tank has near its upper end an internal annular shoulder 7 thatforms support for a cylindrical sleeve 8 which is removably positionedin the tank, there being an external flange 9 at the top of the sleevethat rests upon said shoulder when the sleeve is in position. At thebottom of the sleeve is an internal flange 10 upon which is removablypositioned a preforated plate 11. A layer composed of sponges 12 issuperimposed upon the plate 11, and over said layer is placed a secondperforated plate 13, and in the sleeve above the plate 13 is placed aquantity of filtering material, such as 1924.

charcoal ls. The sleeve 8 has also at a point suitably distant from itsupper endj aa internal shoulder '15 "upon which restsa re-- movableartnered" platel6; *and* in?that pa'rt'of the sleeve above the plate l6are-post tioned a series or reinovable fi lter'ing dr ii'ns ll' arrangedin vertical successive order) Each filtering druinco n "i'ses a hoop 18.upon' which "is laced a head, 'c'omppsed of a series ofjsheets 19 oreoase'woven muslin brotherfabric, '-the margins 20 of the sheets beingfolded over the priineter'of tliefhoop sothat the opening 21 throughthe'hoop" is closed 'hythehead; The drums are forced into positionthroughtheupper end of-the sleeve and are held frictionally in positionbythe pressure of theircontact with the; in: terio'r-wall 'of thesleeve.

In the upper end of the tank 1 is positioned a spider 22, the arms 23 ofwhich rest upon the flange 9 of the sleeve and extend over the series ofdrums. The outer ends of the arms of the spider are clamped between theflange of the sleeve and the head 2 when the latter is secured in placeand thus the upper end of the sleeve is held in close relation with theshoulder 7. i

The lower end of the sleeve terminates at a point suitably distant fromthe bottom of the tank so that when the sleeve is in place therein achamber 24. is left in the lower end of the tank for sediment.

The tank has an inlet opening 25 leading into its settling chamber, andalso an outlet opening 26 leading from a point above the uppermost drum.The tank is supported upon a tubular post 27 that has communication withthe tank at its lowermost point and is closed by a base 28 at its lowerend, there being a draw-oil cook 29 in connection with the post for theremoval of sediment from the chamber 24.

In utilizing the invention the water from the cistern passes through thetank as it is pumped from the cistern, entering the inlet opening 25 andoutthrough the outlet 26, and during its passage the water rises throughthe sleeve and filters successively through the layer of sponges, thepack of charcoal and the drum-heads into the top of the tank from whichit is discharged through the outlet into the distributing pipe (notshown).

Such sediment as accumulates in the settling chamber is periodicallyremoved through the draw-oil cook, and when the filtering material andthe drum-heads become fouled by the accumulations of foreign matter, thesleeve with its content is bodily removed through the top'ott' the tank;Access is gained to the sleeve by first removing the head 2 and thespider. The drums, the charcoal pack and the layer or sponges, as Wellas the several perforated plates are then removed from the sleeve andcleansed in any suitable manner. The filtering substances and materialsare thenreassembled in the sleeve, as'in the first instance, and thesleeve isreplaced in the tank in readiness for resumption of thefiltering'operation.

\Vhat'l claim is: p 1.-Infiltering apparatus, a, closed tank having aremovable head at its top and an internal annular shoulder in its upperpart spaced from the head; removable sleeve in the tank having anexternal flange at its top seated on the shoulder, and an internalflange at its lower end; a series of perforated plates spaced apart andarranged in the sleeve; filter packs in the spaces between theperforated plates; a series of filtering drums positioned in verticalsuccession in said sleev above the uppermostor" said plates, each drumcomprising a hoop and a series of fabric sheets folded over the hoop andclosing the opening thereof; and a spider positioned in the space withinthe tank between the top of the sleeve and the removable head andextending over the series of drums, said tank having an inlet at a pointbeneath the lower end of the sleeve and-an outlet at a point above thetop thereof.

2. In filtering apparatus, a closed tank having an internal annularshoulder in its upper portion spaced from its top; areinovable head atthe top of the tank; a removable sleeve in the tank having at its top anex ternal flange seated on said shoulder ;afiltering means removablylodgen in the sleeve; and a spider clamped by the head upon the flangeof the sleeve and operable to hold the sleeve and filtering meanstherein in position, said tank having an inlet below the lower end ofthe sleeve and an outlet ata point above the top thereof.
